Check Digit Verification of cas no
The CAS Registry Mumber 90614-07-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,1 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90614-07:
(7*9)+(6*0)+(5*6)+(4*1)+(3*4)+(2*0)+(1*7)=116
116 % 10 = 6
So 90614-07-6 is a valid CAS Registry Number.

Reactivity of dinuclear arene ruthenium complexes: Reactions of the hydrido complex [(p-Me-C6H4-Pri)2Ru 2Cl2(μ-Cl)(μ-H)] with NaX and HX (X=F, Cl, Br, I)

The dinuclear hydrido complex [(p-Me-C6H4-Pri)2Ru 2Cl2(μ-Cl)(μ-H)] (1) reacts with the sodium halides NaX in methanol to give the halogen analogues [(p-Me-C6H4-Pri)2Ru 2X2(μ-X)(μ-H)] (2: X=F, 3: X=Br, 4: X=I). With HX, complex 1 reacts to give the tetrahalo complexes [(p-Me-C6H4-Pri)2Ru 2X2(μ-X)2] (5: X=Cl, 6: X=Br, 7: X=I); in the case of X=I, a large excess of HI leads to the formation of the cationic complex [(p-Me-C6H4-Pri)2Ru 2(μ-I)3]+ (8). The X-ray structure analysis of 1 shows a dinuclear Ru2 backbone with two terminal chloro ligands being trans with respect to each other as the two p-cymene ligands, the two bridging ligands lie in a plane perpendicular to the plane defined by the terminal chloro ligands and the ruthenium atoms.
